Clinical Trials

ClinicalTrials.gov is a registry and results database of federally and privately supported clinical trials conducted in the United States and around the world. Users can search by disease name, such as multiple sclerosis.

Current Controlled Trials (part of Springer Science+Business Media) allows users to search, register, and share information about randomized controlled trials. It has two components:

ISRCTN: Allows protocol authors of clinical trials to obtain a unique trial identifier (International Standard Randomised Controlled Trial Number). Any clinical trial designed to assess the efficacy of health interventions in a human population is eligible. Also contains a registry of trials that have been assigned an ISRCTN.

mRCT (metaRegister of Controlled Trials): International database developed by Current Controlled Trials Ltd. that combines information from other trial registries (active contributors currently include ISRCTN and ClinicalTrials.gov).

The EU Clinical Trials Register website allows visitors to search for information on clinical trials in European Union member states and the European Economic Area as well as ones that are conducted outside the EU/EEA if they form part of a pediatric investigation plan.
